Product Description


NOTE 2 : If you are ordering a complete drive unit for a 2014+ pickup model please put that in the notes.  The 2014+pickup models have a slightly different frame and use plastic drive unit top cap with circuit board.  We can build it up for that but just need to know if ordering complete drive unit for 2014+ pickup model.  Put that in the notes of the order please.


*** You Cannot Just Install a Metal Gear Without Also Changing The Motor To The GruvenParts INTERNALLY GROUNDED MOTOR !  You Will Short Out the Body Control Module.  All Of Our Kits Come With New Motors Which Are Internally Grounded and Work With Metal Gears - So Don't Just Replace the Gear, You Must Replace Both Gear AND Motor When Going to Metal !!! ***




 ** Click HERE for the NEW GruvenParts Installation Video **

** Click HERE for the Mirror Gear DIY Article for Full Size GM Trucks **  or (Download PDF)

** Click HERE for the Traverse/Acadia/Outlook Supplemental Instructions **


** 2 Options Are Now Available ***

Note that if you chose Option 2, you will either need to send in your unit for repair directly, or wait approximately 2 months for us to get a unit to repair.  These are becoming hard to find and people arent returning their cores as often anymore for some reason.  We can usually repair sent in units same day to minimize down time as you cant install the mirror without the drive unit in place.

Option 1: 

Buy strengthened steel gears machined integral to the main spiral shaft + hi-torque motor in quantity 1 set for 1 mirror or 2 sets for 2 mirrors ($64.99 / $99.99).  

Option 2:

Buy a rebuilt complete motor drive unit with new hi-torque motor + steel integral gear already installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.

***** PLEASE NOTE WHEN ORDERING THE COMPLETE DRIVE UNIT - If you are in a hurry for this, its best to check with us to see if we have any cores.  It could be 4-6 weeks to receive this, based on how many units we have in the shop.  People do not send back their cores very quickly, so we are usually waiting.  You can send in your own unit to be worked as well, and we will apply the $30 core when you send in and try to work it same day or very quick.  We are currently on a 2 Month Back Order Unless You Can Send In Your Unit to be Rebuilt


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened STEEL gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on 2007-2014 GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened integral spiral spur/worm gear shaft made from high strength steel to eliminate the fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can chose to buy the gear/motor combo for one or both sides or you can buy complete drive units which are rebuilt and already have the new metal gears and hi torque motor installed in them.  

We have thoroughly tested our redesigned integral gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.


** Application ** 

Gears and Motors Fit Both Passenger and Drivers Side Power Folding Mirrors.  

All 2007-2014 GM SUV's With Power Folding Non-Tow Mirrors Including Acadia, Traverse, Enclave, Escalade, Tahoe, Suburban, Yukon, and Denali. 

All 2007-Present GM Pick Up Trucks Including all Silverado and Sierra with Non-Towing Power Fold Mirrors -- please note the 2014+ pick up trucks used different plastics on the frame, so disassembly of the mirror frame doesnt match the DIY.  The lower half of the drive unit with all the gears inside IS the same as the previous generation.

This includes (but not limited to) the following mirror assembly part numbers :

25-83-12-36 (25831236), 25-77-98-49 (25779849)

This list of part numbers will continually grow as we build the interchange list.  This is in no way complete, as most GM trucks made from 2007-2014 with power folding mirrors will use this gear.  If your power folding mirror looks like the mirror shown in the DIY, this gear will fit your vehicle.


... We also have many more products for GM, including the towing mirror gears, 2015-Present SUV non-towing mirror gears, door lock motors, door handle inserts !  Check out the GM section of our website!

  1. great solution and quality! 5 Star Review

    Posted by on 24th Feb 2023

    This is the second time I am using Gruven parts. Verry happy, great instruction videos and happy with results to fix cheap manufactured OEM parts.

  2. Very easy to understand instructions 5 Star Review

    Posted by on 17th Feb 2023

    Fast turnaround on unit repair. Sent in passenger side mirror motor was returned within a few days. However when I received my credit card statement it looks to that you did not give me the $30 dollar credit because I sent you my unit to be rebuilt. You charged me $246.17 which looks like full pop. I understand some of it will be shipping and handling but it does not seem to be right.

    -- William the core refund of $30 takes a few weeks to show back up on your credit card. We do refund core charge for all units sent in that is rebuildable. Please contact me if you dont receive the core refund within a few weeks.


  3. Fantastic Parts & Instructions 5 Star Review

    Posted by on 4th Feb 2023

    Bought these for my 2010 GMC Sierra SLT and they worked beautifully! The step by step instructions they provided in the video made this such an easy process! I will say, that a 15/16 Socket works best for compressing the spring and lock washer! I absolutely recommend these parts as they are miles ahead of what the stock parts are!
